We decided to do central Colombia, basically because it is where the capital is.
We built a model for the number of confirmed cases using all the others covariates (plus some we created) and we estimated the predictive accuracy of our selected model.
We decided to consider as central Colombia the following departments/districts: Bogotà DC, Boyacá, Tolima, Cundinamarca, Meta, QuindÃo, Valle del Cauca, Risaralda, Celdas, Boyacá, Antioquia, Santander, Casanare.
